摘要
It relates to a moving picture coding method and a device having a fast motion estimation algorithm. ; Video encoding method of each macroblock of a representative sub-blocks to obtain the of motion vectors, the calculated representative determining mode by using the relationship between the motion vectors of sub-blocks, and variable block for including a plurality of sub-blocks according to the invention in that it comprises a motion estimation step of estimating motion for the features. ; A moving picture coding apparatus according to the present invention obtains a motion vector of an estimate of the motion of the input image and the motion includes estimating unit that to be used for motion-compensated temporal filtering, representative for the motion estimating unit macroblocks subblocks , characterized in that the motion estimation for estimating a motion of the input image by using the relationship between the motion vectors of the representative sub-block. ; According to the invention it is possible to accurately perform the motion estimation process, which requires a large amount of calculation in a video coding at a relatively high speed. ; Video Coding, H.264, Motion estimation, variable block mode
